BOL'I'ING MECHANISM non GUNS;

To all whom'z't may concern:- I

Be it known that l,- ARTHUR P. Conrrs a citlzen of the United States of America,

kins and-State of New York, have invented certain new and useful Improvements in Bolting Mechanism for Guns, of which the following: is a specification. Y

The primary object of invention is the provision of means in-the nature of-a gun barrel lock,ffor maintaining a gun action securely closed during thefiring operation, and readily releasable for opening whenever desired.

"A. further object ofmy invention 0 provide bolting means for j the frame and barrel of a' gun, transversely -of the latter,. shiftable to and from its-locking POSitl'OIr by means of substantially theusual form 20. v

of 'top lever;

A still further object of my invention is the provision ofa gun action having substantially the usual 'appearance .when. closed, provided: with a suitable form" of transversely positioned bolt i readily looking 1 the frameland barreltogether when the action is closed, the top -leverserving unlocked position.

With these' general objects in view my invention 9 consists of the basic idea of bolting two barrel eXtension lu gs toa gun frame v;or body with'one-boltsetat a right angle to the axis of the bore of the barrel and the'novel construction, combination and ar rangement of parts hereinafter more fully described, illustrated in the accompanying I drawings, and then claimed;

v In the drawingsforming apart of this application "and in I which like 1 reference characters designate corresponding parts throughout the several v ews.

Fig. 7 is a topplan'view of tlie' top' leven.

articulated with the locking boltzand 'Fig; 8 illustrates top and rear sides. and the opposite ends of the bolt.

Referring more'indetail to the drawing, a portion of a gun is illustrated with the frame 10 and barrel" l1 hinged together by.

a pivot-or hinge-pin .1 2 in-the usualzmans nor, the barrel being providedwitlra': fore end iron 13 with tip or fore end of wood 14 while the stock 15 rearwardly extends from the action frame-or body 10. f -Thebreeclrend or rear face=l6 of the ting engagement mvitlithegun action closed,

An elongated bolt "22 slidable transversely of the body 10 in a correspondingly shaped socket '23 in the body freely receives arforin. a longitudinal slot 26 of the bolt, where-1. by the bolt is manually shiftable at. right angles to the axis of thebore-l5 .Tl1e top lever 25-ris pivoted in the top of the body 10. in the usual. manner, such. as by a hub 27 attached to the bottomi of the lever, it beingapparent that the bolt; 22. being normal when the leveri25' is lon'gi tudinally; 'positionedgas shown inaFigs. l-

of the lever 25 .toits extreme right-hand .position,tforci'blyzretracts the-bolt 1221 as. shownin Figs.:-2; and '5'thereof. v z

The inneriendofi the bolt 22 is beveled or; tapered-as at 28 adapted for reception withinnaacorrespondingly tapered.- keeper opening 29 in the extension lug 18 when the bolt is in its locking position.- The lug 17 is pro.-

vided with a recess 30 through which the 100 bolt 22 is slidable during operation when the action is closed, with the lug 17 seated in the groove 19. A. side notch 31 in the bolt 22 permits the lug 17 to pass through said notch for openingthe action when the 105 bolt 22 is projected in its released position aswill be evident from Fig. 5 of the draw ing.

' The complete operationof my invention willbe apparent from this detailed descrip- 110 barrel ll, is. rovided. with parallel lugs correspondingly shaped."

. ward'extension 24 of. the top lever25' with- 1 tion thereof, it being understood that when the top lever is centrally positioned upon the stock 15 and tang of the frame 10, Fig.

4;, and the bolt 22, with the barrel l1 closed, is in ts locked position, extending through the recess of the lug 17 at an unbroken portion of the bolt, whilethe tapered end 28 thereof is seated in the opening 29, of the extension lug 18.

The shifting of the top lever 25 in the usual manner to open the gun action, projects the bolt 22 outwardly of the socket 23, sufficiently to bring the notch 31 in alinement with the lug 17 and the end 28 out ofthe opening 29, whereby the barrel 11 be made therein without departing from the spirit and scope of the invention as claimed. The invention is readily adaptable for different kinds of guns having the opening and closing action, the top lever 25 being furnished with the usual construction of automatic trip for retaining the lever as well 7 as the bolt22 released until the barrel 11 and body. 10 are manually closed.

I claim r 1. A gun comprising pivotally connected body and barrel portions, a bolt transversely shiftable within said body portion having a side notch and tapered inner end, extensions upon said barrel portion having a keeper recess and tapered opening adapted for receiving a side portion and the pointed end of the bolt, when the bolt is in its retracted locking position, the tapered end of p barrel portions, said bolt having a side notch therein adapted to register with the extension having the edgerecess when the end of the bolt when in its projected released position being out of the adjacent path of travel of, one of said extensions, with the notch'opening'at the other of said grooves in the path oftravel of the other extension.

2. In a gun having hingedly connected body and barrel the engaging faces of which are respectively provided with grooves and keeper extensions adapted for reception body and barrel portions, one of said portions beingprovided'with a pair of spaced recesses, the other of said portions being provided with a pair of extensions adapted to be received in said recesses, one of said extensions havinga recess formed in the outer edge thereof and an opening formed in the other extension spaced from the edges thereof,and a bolt ,slidable transversely of the part in which said recesses are formed adapted when moved in onedirection to ex tend into said extension opening and par tially into said extension recess to prevent pivotal movement of the connected body and barrel portions.

1-. A gun comprising pivotally connected body and barrel portions, one of said portions being provided with a pair of spaced recesses, the other of. said portions being provided with a pair of extensions adapted to be received in said recesses, one of said extensions having a recess formed in the outeredge thereof and an opening formed in the other extension spaced from the edges thereof, a bolt slidable transversely of the part in which said recesses are formed adapted when moved in one direction to extend into said extension opening and partially into said extension recess'to prevent ivotal movement of the connected body and said bolt is removed from the extension openin to permit a pivotal separating movement of the body and barrel portions.

In testimony whereof I affix my signature.
